Through 2013 the Trust worked with a group of committed volunteer Tree Wardens in North Somerset to survey nearly 200 sites across the District to collect information on any trees present. This information, along with climatic data for the survey period, has now been processed using the US Forestry Service’s iTree model.
The results graphically set out the invaluable pollution management services that North Somerset’s trees provide. They also demonstrate the huge contribution that volunteers can make and this project is the first to use volunteers to collect information in the UK.
In North Somerset, tree cover removes harmful pollutants (CO, NO2, O3, PM10, PM2.5, SO2), with an annual average value of £1,703,648.30. This is another compelling reason why we need to look after our existing trees and plant more of them.
The iTree model can be applied at a variety of scales ranging from a local authority to a Parish or Ward, or a local park/ green space. The Trust can provide a free introductory meeting, or a detailed briefing for £125. Details of these and other services are here: iTree Flyer Text_1.
